Question
For performing the 2 Sample T Test, what is NOT an assumption?
Solution
The assumption that is NOT required for performing the 2 Sample T Test is that the two populations must have the same variance. This is not a necessary assumption because there are versions of the T Test (like the Welch's T Test) that can be used when this assumption is violated.
